Season the shrimp with salt and pepper.
Heat up a cast-iron skillet to medium-heat. Add the olive oil, garlic and lightly sauté before adding the shrimp. Stir and cook until the shrimp are halfway cooked and flip them over.
Add the cilantro and butter, stir to combine with the shrimp. Add the lime juice and continue to cook the shrimp until pink on both sides.
Turn off the heat when done and serve immediately. Serve with pan sauce drizzled over top.
